AI app builders

Make your AI-built contact form send email

Lovable, Bolt.new, and similar tools build a great-looking form fast — but it usually has nowhere to send. One prompt wires it to PostTo instead.

Lovable contact form

Make the contact form in your Lovable app send email. One prompt, one endpoint URL — no Supabase Edge Function, no email provider to configure.

Bolt.new contact form

Make the contact form Bolt.new built send email. One prompt, one endpoint URL — no Supabase Edge Function, no email provider to configure.

v0 contact form

Make the contact form v0 generated actually send email. One prompt, one endpoint URL — no Next.js API route or Vercel environment variable to configure.

Replit Agent contact form

Replit Agent scaffolds a full Express backend and database for your app. Skip building the email-sending part for a contact form — point it at PostTo instead.

Base44 contact form

Make the contact form Base44 built actually send email — no backend function, no Pro-plan upgrade, no database entity with nowhere to go.

Don't see your builder?

The same prompt pattern works for any AI builder that generates a plain fetch call or HTML form. Replace YOUR_TOKEN with the endpoint URL from your dashboard and paste this into its chat.

Generic prompt — works with most AI app builders

Update the contact form's submit handler to send its data to PostTo instead
of just showing a fake success state. On submit, POST the form fields as
JSON to https://postto.dev/api/v1/send/YOUR_TOKEN with a "Content-Type: application/json" and
"Accept: application/json" header. Show the existing success state if the
response is ok, and the existing error state otherwise. Add a hidden "_hp"
honeypot input that real visitors never see. Keep all other current fields,
validation, and styling unchanged.
